Recently, as recognizing the risk about the infection of an infectious wastes, the problems about the management and treatment of the infectious wastes stand out socially. In this paper, as being possible monitoring whole processing from the origin of the infectious waste to the processing plant, using the RFID which is the kernel technology of the next generation, we tried to solve the second infection problem by inefficient treatment of the infectious wastes. Through the research suggesting in this paper, as storing and monitoring the procedural business articles and the problem about miss-writing and input error being found in management system like documentary writing by the existing manager and computation input by the web application, we can understand the management state, immediately. And the Bio information for the personal authentication is carried out through storing the feature vector calculation by the PCA algorithm, into the tag. It suggested more systematic and safer management plan than previous thing, as giving attention about the wastes to manager.

Environmental accounting identifies and measures environmental costs and provides them to interested parties of corporation. The purposes of this study are as follows: First, it investigates the method of measurement and the timing of recognition of environmental costs. Second, it suggests the method of disclosure of environmental costs. In order to accomplish these objectives, this study reviewed relevant literature and studies in advanced countries and Korea. The main results of this study can be summarized into four points: (1) environmental costs are classified into environmental pollution cost and environmental pollution prevention cost, by considering the sources of occurrence of, the functions of and the types of environmental costs. (2) the methods of measurement of environmental costs are various but they almost all subjective and arbitrary. So an accurate measurement of environmental cost is actually difficult. (3) According to the accrual basis, environmental costs are recognized respective to prior period adjustments, expenses or losses of the current period and the assets of the next period. (4) There are 3 methods of disclosure of environmental costs: an extension model of financial statements, a compromise model, and an original model. An extension model financial statements is easy to apply in business practice because it discloses environmental costs by adding accounts into the framework of a traditional accounting system or supplementary reports. This research can contribute to the establishment of accounting standards for environmental costs in Korea.

예상은 하고 있었던 일이지만, 준비없이 갑작스럽게 다가온 1993년 중국과의 국교정상화는 우리에게 무의미한 대가를 적지않게 하였다. 그리고 이후 이미 8년이란 세월이 흘러갔어도 잘못 끼운 첫 단추의 부담은 여전히 해결하지 못한, 아니 어쩌면 영원히 해결할 수 없을 것만 같은 숙제로서 남겨져 있다. 특히 손상된 민족의 자존심은 경제적인 실리를 떠나서 제2의 조공시대를 방불케 하는 신사대주의의 한중관계를 만들어 버리고 말았다. 최근 들어 IMF이후 주춤했던 중국을 향한 건축계의 막연한 기대가 2010년 북경의 올림픽 유치확정을 계기로 서서히 달아오르는 느낌을 받는다. 게다가 일부 언론매체의 보도는 벌써부터 앞으로 발주될 100억 달러 이상의 건설시장경기를 들먹이며 우리의 떡이 어느 정도인지 저울질하는 웃지 못할 모습을 보이고 있다. 물론 의욕과 열정을 무조건 탓하는 것도 잘못이지만 일에는 순서가 있는 법이며 지나친 무리수는 결과적으로 과역과 과열이라는 쓰라린 경험을 남기기 십상이다. 지금 이 시점에서 우리가 할 일은 분명하다. 우리의 현실을 직시하고 저들의 현실을 정확히 파악하며 국제적인 추세를 냉철하게 읽어내는 것이다. 중국의 건설시장에 관해서는 이미 1995년 12월호 '건축'잡지에서 '중국의 건축'이라는 특집을 통해 부분적으로 소개된 바 있고, 2001년 9월호 '건축인'에서도 '중국건축:건설시장, 아직도 기회는 있는가'라는 주제를 다룬바 있다. 뿐만 아니라 일부 설계사무소가 자신의 실제 작업경험을 다양한 지면을 통해 간헐적으로 소개하는 한편, 지금 이순간에도 자신들 나름대로 중국건축업계와 협력관계를 구축하여 진행하는 일이 적지 않다. 이 글은 우리나라의 대표적인 건축설계사무소 가운데 하나인 (주)무영종합건축사사무소가 중국시장에 진출하는 과정(즉, 이 과정은 비교적 총체적인 것임)에서 얻은 경험을 진솔하게 밝혀 한국건축계의 동료들과 자료를 공유하여 동일한 오류를 범하지 않도록 하고자 하는데 그 근본적인 목적이 있으며, 참고로 최근 중국 건설시장의 동향을 가능한 한 상세하게 소개하고자 한다.

Various placards are attached to the surface of a container depending on the risk of the cargo loaded. Containers with dangerous goods should be managed separately from ordinary containers. Therefore, as part of the port automation system, there is a demand for automatic recognition of placards. In this paper, proposed is a system that automatically extracts the placard area based on the shape features of the placard and recognizes the contents in it. Various distortions can be caused by the surface curvature of the container, therefore, attention should be paid to the area extraction and recognition process. The proposed system can automatically extract the region of interest and recognize the placard using the feature that the placard is diamond shaped and the class number is written just above the lower vertex. When the proposed system is applied to real images, the placard can be recognized without error, and the used techniques can be applied to various image analysis systems.

Containers are fitted with various placards on the surface to indicate the risk of cargo. If the containers are loaded with dangerous goods, care should be taken in handling the containers. Therefore, as part of the port automation system, there is a demand for automatic placard recognition. In this paper, proposed is a method to extract placard areas from a container image, which is the first part of the placard recognition system. The fact that placards are of various types but all have a diamond shape can be an advantage in recognition. However, it is a disadvantage in recognition that the placards can be distorted in various ways because the container surface is not flat. When the proposed method was applied to actual images, type I error did not occur. In addition, since the shape feature of the object and basic image operations are used to extract regions of interest, it can be applied to various shape-based region extraction problems.

In this article, the Medical Act, the Emergency Medical Act, Act on remedies for injuries from medical malpractice and mediation of medical disputes were reviewed and interpreted based on the Civil Act. In the health and medical field, there are various laws that reflect changes in the medical field due to the development of health and medical technology, and their revision is very frequent. And the legislation has become very complicated. They contradict each other or require interpretation. In this situation, a person must take considerable care not to violate the law. In many cases, specific guidelines or authoritative interpretation are required to apply the law. Even guidelines and authoritative interpretations often conflict with civil law. In this article, errors in the legal text related to health care were found. In addition, it found a case that contradicts the civil law perspective in interpretation. Thus, it was confirmed that civil legal thinking was necessary to legislate, interpret, and apply health care-related laws.

Malrotation and midgut volvulus are surgical emergencies that commonly occur within the first month of life. The classic symptom is acute bilious vomiting, while nonspecific symptoms such as recurrent abdominal pain may be present in older children. Malrotation can be associated with duodenal obstruction caused by an abnormal peritoneal fibrous band or congenital anomalies, such as an annular pancreas or a preduodenal portal vein. Volvulus can lead to bowel ischemia and a life-threatening condition, thus prompt and accurate diagnosis is crucial. Diagnosis can be made through upper gastrointestinal series, ultrasonography, and CT, with ultrasonography being preferred as a screening tool due to its rapid and accurate diagnosis, without radiation exposure, in children. This pictorial essay discusses the key imaging findings and diagnostic approaches for malrotation and midgut volvulus, as well as diagnostic pitfalls based on actual cases.

This study examines how the watchdog concert in journalism field has been created and develope4 Related studies found that the watchdog is related not so muck with free press theory as with a privilege awarded to the press because the press serves for the public interests. It was found that in the U.S., the watchdog concept was derived from the a lot of libel cases in the late 1890s. At the time, the newspaper owners and editors continuously claimed the very protection over vulnerability of newspaper's collecting, reporting, and printing news. While, in Korea, the concept of watchdog emerged in the late 1990s after the establishment of the Constitution Court. Even though the watchdog concert was accepted very late by the Korean courts, it is believed to be a kind of special privilege to prevent the press from being recklessly regulated in libel cases. Rather, the Korean courts expand the extent of the role of the press as a watchdog by deciding that not only the public officials and politicians but also other socially influential public figures could be included in the criticism from the press. However, how these court decisions can be practically implemented depends upon how the court apply the probability of the press to believe the news true and intention of malice in writing and publishing the stories.

This study was to identify middle school and college of education students' preconceptions about dielectric polarization and explore the students' reponses on the supporting or conflictual evidences on their preconceptions by letting them observe the demonstrations using electroscope, charged material, six conductor rods and six insulator rods. Letting students select the demonstrations to be observed by themselves, students' evidence selection types were classified as two : to select the evidences to testify their uncertain preconceptions, and to obtain the confirmation evidences about their preconceptions. And each evidence selection types, again, could be subclassified as three and two respectively. When students observed the conflictual observations, all accepted the observation itself. For supporting observational evidences, almost of all students showed the error of 'acceptance of antecedent' in the syllogism, that is, they did not required the succeeding supporting observations. Students' reponses on the conflictual observational evidences were classified as two: to reject the hard core of preconceptions, and to modify the students' auxiliary ideas related to the hard core with preserving the hard core. The first type reponses were, again, could be classified as three subtypes but, in all cases, students introduced new concept to explain the conflictual evidences. This responses indicated that Lakatosian rather than Popperian view is more acceptable to understand the students' reponses on the conflictual evidences. The second type reponses also were classified as three subtypes, and it was found that more middle school students than college education students were involved in this second type. That is, students who did not have perfect understanding of auxiliary ideas related with the hard core of preconceptions were more apt to change or modify theses auxiliary ideas rather than reject the hard core, this means that the quality of understanding of auxiliary ideas also take an important role in the change of hard core concept.

In this study, we are interested in the teachers' MCK about '$N{\div}0$' and MPCK in relation to the proper ways to teach it. Even though '$N{\div}0$' is not on the current curriculum and textbooks of elementary school mathematics, a few students sometimes ask a question about it because the division of the form '$a{\div}b$' is dealt in whole number including 0. Teacher's obvious understanding and appropriate guidance based on students' levels can avoid students' error and have positive effects on their subsequent learning. Therefore, we developed an interview form to investigate teachers' MCK about '$N{\div}0$' and MPCK of the proper ways to teach it and carried out individual interviews with 30 elementary school teachers. The results of the analysis of these interviews reveal that some teachers do not have proper MCK about '$N{\div}0$' and many of them have no idea on how to teach their students who are asking about '$N{\div}0$'. Based on our discussion of the results, we suggest some didactical implications.
